Noted. Appreciate the heads-up.Looks good. Be mindful if you have never been on Southwood Rd 13 (near Bala), that it is quite twisty with pretty crap road quality. Expect to have frost heaves in mid corner as well as gravel, sand and potholes. Slow right down for the two railway crossings - they are in poor condition.
I still say go for it to experience it, but if that is the last twisty road on your ride, then maybe take a quick break before in Bala, so your mind will be alert.
